Strange one -_-
« on: 16 February 2014, 11:16 »
Ok so was driving the car back from Liverpool on sat morning and noticed, say your at 3000rpm you have access to full boost (20psi) but say I put my foot down only half way so I would only boost upto 10 psi the car would splutter and judder but if I put my foot all the way down on full boost not a drama and no fault

Any ideas?

leaky boost when half throttled, possible that one of your pipes only seals under full throttle with the amount of pressure being forced through, check all your connections, alternatively and possibly a good idea, get some electrocleaner for about £3 a can and spray your MAF with the whole can.

Just went for an pre MOT and the pipe that goes frm the charge pipe to pancake pipe has a split/ crack so that's probably it

Cheers buddy legend :)
